Lyft, the No. 2 U.S. ride service by ride volume, in a statement said a deal to launch self-driving pilots would accelerate its vision for transportation. Waymo, which is beginning tests of a self-driving car service in Phoenix, said the partnership would let its technology reach “more people, in more places”.

Neither offered many details of the agreement, which was reported earlier by the New York Times.

The auto industry and technology companies are racing to develop self-driving technology, which they expect in a number of years will transform transportation, cutting costs of ride services and changing the way people buy and use cars.
